I would say, get a cat. Or is that cruel? Nice video, never seen this so clearly. I am going to dig a pond myself, and as your garden, it is full of stones and rocks. And I too have an office job, so your videos are inspirational. First some reconstruction in and around the house to do, which probably will mess up the garden, so I’ll wait until that is finished. Thanks for uploading, please keep posting videos about ponds and gardening in general.
